Nested Controllers in Laravel 4 -

I'm new to laravel4, and there is a problem for the installation of nested controllers. I have an "admin" sub in my controller directory -Directory is where the administrator is the controller. My admin administrators extend "AdminController" to my controller directory. I have admin admin controllers like this

   Content = View :: Create ('admin.dashboard'); }}   
 And in my routes. Php file  
  / ** Admin path ** / Root :: Groups (array ('domain' = & gt; 'Admin.vigap.local'), function () {// dashboard Root :: Mill ('/', 'Admin \ HomeController @ Index');});   
 But when I navigate, I get an error by saying "class admin" not found ". What am I doing wrong?   
 
 
 How your administrator works, nothing wrong with the Home Controller you use  Admin  namespace , Then you call the  View  class in the index function, but that category is not part of the  Admin  namespace and therefore you should An error will be found that  class admin \ view  was not found.  
 Try one of the following two things:  
  see usage   
 or  
  $ this-> layout-> content = \ view :: create ('admin.dashboard');   
 (Note backslash in front of  view )
